If Red Rock doesn't do it for you, keep driving. Eventually you'll hit this park. Pack a picnic because there's nothing nearby and it's practically half an hour away from civilization. Also, duh, it's a park. What else were you planning to do there?
I have really mixed feelings about it: in the right weather, or if you time your visit for dusk, it's gorgeous and the meadow area has grazing sheep and goats. The walkway is lit by eco-friendly solar-powered lights and there's a path paved with decorative stones engraved with the names of donors and positive messages. The Super Summer Theater has shows out here June-August.
But goddamn is it oddly similar to the surface of the sun. There's a lot of animal droppings (maybe not the best pick if you're toting kids). The parking area is not paved (minor complaint). And it is WAY out there, the word "remote" comes to mind. Probably a good choice for hiding a body. Unless I've missed something (entirely possible) there isn't much in the way of trails out here? Look it up prior to your visit just in case, and print any materials you find- there's no reception out here.
